Abstract
In this study, the Euler–Euler (E–E) and Euler–Lagrange (E–L) models designed for the same chemical mechanism of heterogeneous reactions were used to predict the performance of a typical sudden-expanding coal combustor. The results showed that the current E–E model underestimated the coal burnout rate because the particle temperature fluctuation on char combustion is not adequately considered. A comparison of the E–E and E–L simulations showed the underestimation of heterogeneous chemical reaction rates by the E–E model.
